1 | .TH ELVIS 1 |
2 | .SH NAME | |
3 | elvis, ex, vi, view, input - The editor | |
4 | .SH SYNOPSIS | |
5 | \fBelvis\fP [\fIflags\fP] [\fB+\fP\fIcmd\fP] [\fIfiles\fP...] | |
6 | .SH DESCRIPTION | |
7 | \fIElvis\fP is a text editor which emulates \fIvi\fP/\fIex\fP. | |
8 | .PP | |
9 | On systems which pass the program name as an argument, such as Unix and Minix, | |
10 | you may also install \fIelvis\fP under the names "ex", "vi", "view", and "input". | |
11 | These extra names would normally be links to elvis; | |
12 | see the "ln" shell command. | |
13 | .PP | |
14 | When \fIelvis\fP is invoked as "vi", | |
15 | it behaves exactly as though it was invoked as "elvis". | |
16 | However, if you invoke \fIelvis\fP as "view", | |
17 | then the readonly option is set as though you had given it the "-R" flag. | |
18 | If you invoke \fIelvis\fP as "ex", | |
19 | then \fIelvis\fP will start up in the colon command mode | |
20 | instead of the visual command mode, | |
21 | as though you had given it the "-e" flag. | |
22 | If you invoke \fIelvis\fP as "input" or "edit", | |
23 | then \fIelvis\fP will start up in input mode, | |
24 | as though the "-i" flag was given. | |
25 | .SH OPTIONS | |
26 | .IP \fB-r\fP | |
27 | To the real vi, this flag means that a previous edit should be recovered. | |
28 | \fIElvis\fP, though, has a separate program, called \fIelvrec(1)\fP, for recovering | |
29 | files. | |
30 | When you invoke \fIelvis\fP with -r, \fIelvis\fP will tell you to run \fIelvrec\fP. | |
31 | .IP \fB-R\fP | |
32 | This sets the "readonly" option, | |
33 | so you won't accidentally overwrite a file. | |
34 | .IP "\fB-t\fP \fItag\fP" | |
35 | This causes \fIelvis\fP to start editing at the given tag. | |
36 | .IP "\fB-m\fP [\fIfile\fP]" | |
37 | \fIElvis\fP will search through \fIfile\fP for something that looks like | |
38 | an error message from a compiler. | |
39 | It will then begin editing the source file that caused the error, | |
40 | with the cursor sitting on the line where the error was detected. | |
41 | If you don't explicitly name a \fIfile\fP, then "errlist" is assumed. | |
42 | .IP \fB-e\fP | |
43 | \fIElvis\fP will start up in colon command mode. | |
44 | .IP \fB-v\fP | |
45 | \fIElvis\fP will start up in visual command mode. | |
46 | .IP \fB-i\fP | |
47 | \fIElvis\fP will start up in input mode. | |
48 | .IP "\fB-w\fR \fIwinsize\fR" | |
49 | Sets the "window" option's value to \fIwinsize\fR. | |
50 | .IP "\fB+\fP\fIcommand\fP or \fB-c\fP \fIcommand\fP" | |
51 | If you use the +\fIcommand\fP parameter, | |
52 | then after the first file is loaded | |
53 | \fIcommand\fP is executed as an EX command. | |
54 | A typical example would be "elvis +237 foo", | |
55 | which would cause \fIelvis\fP to start editing foo and | |
56 | then move directly to line 237. | |
57 | The "-c \fIcommand\fP" variant was added for UNIX SysV compatibility. | |
58 | .SH FILES | |
59 | .IP /tmp/elv* | |
60 | During editing, | |
61 | \fIelvis\fP stores text in a temporary file. | |
62 | For UNIX, this file will usually be stored in the /tmp directory, | |
63 | and the first three characters will be "elv". | |
64 | For other systems, the temporary files may be stored someplace else; | |
65 | see the version-specific section of the documentation. | |
66 | .IP tags | |
67 | This is the database used by the \fI:tags\fP command and the \fB-t\fP option. | |
68 | It is usually created by the \fIctags(1)\fP program. | |
69 | .IP ".exrc or elvis.rc" | |
70 | On UNIX-like systems, a file called ".exrc" in your home directory | |
71 | is executed as a series of \fIex\fR commands. | |
72 | A file by the same name may be executed in the current directory, too. | |
73 | On non-UNIX systems, ".exrc" is usually an invalid file name; | |
74 | there, the initialization file is called "elvis.rc" instead. | |

79 | .SH BUGS | |
80 | There is no LISP support. | |
81 | Certain other features are missing, too. | |
82 | .PP | |
83 | Auto-indent mode is not quite compatible with the real vi. | |
84 | Among other things, 0^D and ^^D don't do what you might expect. | |
85 | .PP | |
86 | Long lines are displayed differently. | |
87 | The real vi wraps long lines onto multiple rows of the screen, | |
88 | but \fIelvis\fP scrolls sideways. | |

95 | Many other people have worked to port \fIelvis\fP to various operating systems. | |
96 | To see who deserves credit, run the \fI:version\fP command from within \fIelvis\fP, | |
97 | or look in the system-specific section of the complete documentation. |
